Last of the Big China Love-Ins

China is within striking distance of locking down its biggest-ever overseas acquisition, after China National Chemical Corp. won U.S. and European Union antitrust approval for its $43 billion takeover of Swiss pesticide maker Syngenta AG. Just as well, because it may be the last big deal in a while.

Although the transaction still needs the green light from regulators in China, India and Mexico, it's hard to see why any of those jurisdictions would turn it down. China is keen to get its hands on Syngenta's seed technology. Beijing faces the tough task of trying to feed 21 percent of the world's population with 9 percent of its arable land, and know-how from the Swiss giant would go a long way. India and Mexico, meanwhile, don't have a history of rejecting large global deals.
